ABC News’ Christine Byun Reports: As he prepares to head out to Iowa, Republican presidential hopeful Fred Thompson weighed in on "Huckmentum" – the rise of former Arkansas Governor Mike Huckabee.
"We’re gonna look back on it, and it’s either going to be part of something big, or it’s going to be a bubble … We don’t know the answer to that," Thompson said in an appearance on "Face the Nation."
He also continued to question Huckabee’s record.
"If you look at his policies, liberal is the only word that comes to mind when he was governor," Thompson said, criticizing Huckabee for raising taxes while he governed in Arkansas.
However, Thompson recognized his fellow Southerner has been able to mobilize Christian conservatives, which Thompson acknowledged could "do you a lot of good politically."
When asked by host Bob Schieffer about another rival, former Massachusetts Governor Mitt Romney, Thompson said he’s unsure of "how you would determine Mitt would govern in the future, if you look at his past and where he stands today."
"Mitt’s taken different positions at different times before different audiences at different times of his plan and career," Thompson said, later adding, "With me, you know what you get. I am who I am and that’s who I’ve always been."
